CNN boss Jeff Zucker slammed Mark Zuckerberg’s Facebook at Tina Brown’s first Women in the World Canada Summit, saying, “I urge more folks to hold them to account” for taking ads in a Russian-backed campaign to influence the election.

“I think it is outrageous that Facebook will not be more transparent about the advertising they took from Russia, and show those ads and release more information,” Zucker said of the social-media platform. He added, “Facebook’s behavior . . . has not been transparent and this is a huge issue. I urge more folks to hold them to account.”
